Basement Finishing Contractors in Toronto
Your basement is the most underused space in your home. Finished properly, it adds a bedroom, an office, a family room — and real value at resale. VMB Group's crews finish basements across Toronto to code, on schedule, and with the permits done right.
We handle everything from framing to final paint: insulation, drywall, flooring, pot lights, bathroom rough-in, egress windows, and trim. One contractor. One contract. No coordinating between trades.
What Basement Finishing Includes
"Finishing a basement" means converting unfinished space — bare concrete, exposed joists, raw walls — into habitable living area. The scope depends on how you intend to use the space and what the building code requires for that use.
Standard basement finishing package:
- Framing (steel or wood stud walls, ceiling soffit)
- Spray foam or batt insulation (walls and rim joist)
- Drywall and taping
- Pot light installation (LED, on dimmers)
- Electrical outlets, switches, and panel circuits (by licensed electrician)
- Flooring (LVP, tile, or carpet over concrete subfloor)
- Painting (walls, ceiling, trim)
- Door installation (interior + cold room door if applicable)
Common additions:
- Bathroom (half-bath or full — framing, plumbing rough-in, tile, fixtures)
- Egress window (required by Ontario Building Code for any bedroom use)
- Wet bar or kitchenette
- Laundry room
- Home office with dedicated circuits and data rough-in
- Heated floor (under tile or LVP)
- Gas fireplace rough-in
Before Finishing: What Needs to Be Checked
A basement is only ready to finish when three conditions are met. Skipping any of these causes expensive problems after the walls are up.
1. No moisture entry
Any crack or joint that allows water in needs to be sealed before framing. Moisture trapped behind drywall leads to mold within 12–18 months — and remediation costs far more than the original repair. We inspect every wall and floor joint before work begins and flag anything that needs to be addressed first.
2. Adequate ceiling height
Toronto's building code requires a minimum finished ceiling height of 6'5" (1.95m) for habitable rooms. Most homeowners want 7'6" or more for a comfortable space. If your basement is below that threshold, underpinning is required before finishing begins. We assess this at the estimate.
3. Structural integrity
Foundation walls with active movement or horizontal cracking need to be stabilized before framing is attached. We check for this during the inspection. If issues are found, we address them — we don't frame over problems.
If your basement passes all three checks, we can go straight to finishing. If not, we'll tell you what preparation is needed and what it costs.
Basement Finishing Cost in Toronto
The cost to finish a basement in Toronto depends on the size of the space, the level of finish, and what extras (bathroom, egress window, wet bar) are included.
Cost per square foot — interior finishing only:
Finish level | Included | Cost per sq ft |
Basic | Framing, insulation, drywall, flooring, paint, pot lights | $60 – $85/sq ft |
Mid-range | + Bathroom (half or full), egress window, custom ceiling | $90 – $120/sq ft |
High-end | + Wet bar, heated floors, built-in millwork, home theatre rough-in | $120 – $160/sq ft |
Typical total cost to finish a basement in Toronto:
Basement size | Basic finish | Mid-range | High-end |
600 sq ft | $36,000 – $51,000 | $54,000 – $72,000 | $72,000 – $96,000 |
800 sq ft | $48,000 – $68,000 | $72,000 – $96,000 | $96,000 – $128,000 |
1,000 sq ft | $60,000 – $85,000 | $90,000 – $120,000 | $120,000 – $160,000 |

- Egress window cut-through in concrete foundation wall ($2,500–$4,500)
- Heated floors (adds $3,000–$8,000)
- Electrical panel upgrade if existing panel is at capacity
- Low ceiling height requiring bulkheads and careful layout

Permits for Basement Finishing in Toronto
This is where many homeowners make a costly mistake: finishing without permits.
In Toronto, a building permit is required when:
- The finished space will include one or more bedrooms (egress window required by code for each bedroom)
- You’re adding a bathroom (plumbing permit)
- You’re making significant electrical changes (electrical permit)
- You’re creating a secondary suite / rental unit (separate permit process)
Why permits matter:
- Ontario requires sellers to disclose unpermitted work
- Unpermitted finished basements show up in home inspections and can kill a sale or require remediation before closing
- Insurance may not cover damage in unpermitted spaces
- The City of Toronto does issue after-the-fact permits, but the process is expensive and sometimes requires opening walls
This is where many homeowners make a costly mistake: finishing without permits.
Egress Windows for Basement Bedrooms
If any room in the finished basement will be used as a bedroom — or described as a bedroom at resale — Ontario Building Code requires an egress window. This is a minimum-sized window that allows a person to exit in an emergency.
Ontario minimum egress window requirements:
- Minimum clear opening width: 380mm (15″)
- Minimum clear opening height: 380mm (15″)
- Minimum clear opening area: 0.35 m² (3.77 sq ft)
- Maximum sill height from floor: 1,000mm (39″)
Cutting an egress window through a concrete foundation wall is structural work — it requires proper lintel installation and permit. VMB Group does this as part of the finishing package.
Cost: $2,500 – $4,500 per window opening depending on wall type and depth of cut.

Frequently Asked Questions (FAQ)
How much does it cost to finish a basement in Toronto?
Basic finishing (framing, drywall, flooring, paint, pot lights) runs approximately $60–$85 per square foot. A mid-range finish with bathroom and egress window is typically $90–$120 per sq ft. For an 800 sq ft basement, expect $48,000–$96,000 depending on scope. We provide itemized written estimates based on your specific basement.
What is the average cost to finish a basement in Toronto?
Based on current Toronto contractor rates, most homeowners finishing a standard 800 sq ft basement spend $55,000–$85,000 for a mid-range finish including bathroom. Higher-end finishes or those requiring egress window cuts, wet bars, or heated floors will exceed this range.
Do basement finishing contractors in Toronto include permits?
VMB Group does — permit applications and inspections are included in our scope. Be cautious of contractors who quote significantly below market and exclude permits: unpermitted basement work is a liability at resale and may not be covered by insurance.
How long does basement finishing take in Toronto?
Typically 8–14 weeks from permit approval to completion for a standard basement. The permit approval process (currently 2–6 weeks at the City of Toronto) is often the longest phase. We apply early and schedule crews accordingly.
Do I need a permit to finish my basement in Toronto?
Yes, in most cases. Any finished basement that includes bedrooms, a bathroom, or significant electrical work requires a building permit. Basic storage or utility work may not. We advise on the permit requirements for your specific scope at the estimate.
What's the difference between basement finishing and basement renovation?
Finishing refers to converting unfinished space to liveable area — framing, drywall, flooring, fixtures. Renovation is broader and often includes structural work (underpinning, waterproofing) as a prerequisite. If your basement needs ceiling height or has moisture issues, you need renovation first, then finishing. VMB Group does both. See our full basement renovation page →
